KNOCKDOWN BOX.

To all whom it may concern:

Be it known that I, JOSEPH L. WVARE, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvemerits in Knockdown Boxes, of which the following is a specification.

My invention relates to boxesadapted for! packing, storin or shipping purposes; and

- the ob ect ofthe invention to provide a part of this specification; Figure 1 is a persame.

Fig. 8 is a plan view of one o the blanks forming the sides and ends of the box, showing additional posts or supports arranged on the blank in position to e in the center of each side of the'com'plete box.

In constructing this box I provide a continuous sheet 2 of flexible. material, preferably wood-pulpboard which is selected on. account of its strength and tenacious character. form the sides and ends of the box that it is desired to construct. I also rovide the top and bottom rails 3 and 4, eac of which is of the same len th as the sheet of pulp and I form diagonally in each rail a slot 5 extending the full length thereof. -These slots are cut deep enough so that when the ed es of the sheets are inserted therein the rail may be closed together so as to clamp the edge of the sheet between the walls of the slot, and said edges'are then looked in place by nails 6 driven through the rail and .through the These blanks may be'shipped in this orm, together Specification of Letters Patent.

with the flat tops and bottoms for the boxes, thereby giving the shipper the advantage of the low freight rate to which the boxes in knock-down form are entitled.

When it is desired to set up the box, the

top and bottom'rails are sawed through at the points where the corners are to be (see Figs. 5 and 6) and the blank is then bent into rectangular form. This furnishes the sides and ends for a rectangular box of any dimensions with a smooth interior surface, andwithout any joints at the corners, except at the one corner where the ends of the blank meet (see Fig. 6). I then provide a corner post 7, preferably of rectangular form in cross section and of su'llicient area to fill the space formed by turning the sections of the to and bottom rails at right angles to each ot er. I preferably secure these posts to the ends of the rail sections by the right-angled ,75

metallic straps 9 (see Figs. 1 and 3), and I also prefer to provide upon each inner side of the corner post 7 the supporting strip 8. These strips are of preferably the same width. as the corner ner space is thus ormed between them, which receives the corner of the continuous sheet at three of the corners of the box. At

the other corner the ends of the sheet are carried between one of the supporting strips may "also provide additional supporting stri s 10 at intervals extendin from the top to t 1e bottom rail outside of t 1e pulp board sheet (see Fig. 8). These strips may be applied to" the'continuous blank, before the rails are cut across to permit the foldinga of theblank into shape for the box body.

varied in many particulars without departor: panel of flexible material having its'longitudinal edges secured in said slots and bent and inexpensively secured together and shipped in flat form to the customer, It is l only necessary to divide the continuous rails into sections of suitable length to form the sides and ends according to the size and, shape of box desired. The material used is E inexpensive, being small pieces of low grade lumber and sheets of wood pulp or similar material of suitable gage. The panels or walls of the box are held in the slots in the rails and the inner surface of each panel is substantially flush with the corresponding surfaces of the rails and allows the contents to be .snugly packed and permits the convenient and rapid filling or emptying of the The smooth interior of the box also presents a neat finished appearance and adapts it particularly for packing such articles as crackers, biscuits, etc. The metal straps on the corner posts brace and strengthen the box to a considerable degree, but Whenever desired these'straps may be omitted and the posts merely nailed to the The box is practically water tight and any number of boxes when filled with any material which it may be desired to ship therein,. may be piled one on top of anotherwithout' crushing.

' The boxes are accepted by the railroads at the same rate of freight as is provided for ordinary wooden boxes which is not the case with the usual packages formed of paper or wood pulp. I

The details of the construction may be ing from my invention.

I claim as my invention 1. A box blank "comprising parallel rails and an intermediate flexible panel having portions thereof adjacent to the rails deflected and inclosed within the rails, one surface of the panel and the corres ending faces of the rails being substantial y flush with each other, and said rails being transversely severed at intervals to ermit the blank to be bent to form the wal s of a box with the rails extending parallel therewith, substantially as described. I

2. A knock-down box having wooden strips forming the top and bottom rails of the sides and ends of the box, each, of said stri s being provided upon its inner surface wit a diagonal slot extending throughout the length of saidstrip, a continuous sheet or folded at right angles to form'the corners corner tween the contiguous ends of the top and and end rails and bearing on said panel corners, and supporting strips secured to said osts etween the top and bottom rails, su stantially as described.

4. A knock-down box having side and end rails for the top and bottom of the box, each having longitudinal slots therein, a contin-.

uous flexible sheet or tudinal edges secured ting into the spaces between the contiguous ends of the side and end rails, and metallic straps securing said posts to said rails, substantially as described.

5. A knock-down box having a flexible plate or )anel, and strips secured to the upper anrf lower edges of said plate or panel on one side thereof to form top and bottom rails for the sides and ends of the box, said strips being transversely cut at points corpanel having its longiresponding to corners of the box, and said panel being bent at such points to bring portions thereof into position to form the "sides and ends of the'box, and said strips into position leaving spaces between their adjacent ends at their points of severance, and pieces filling said spaces, substantially as described. I

6. A knock-down box having top and bottom rails for the sides and ends of the box, and a-flexiblc panel or plate having its longitudinal edges secured to said rails and its inner surface flush substantially with the corresponding surface of said rails, said panel being bent toform the corners of the box. and the adjacent ends of said top and bottom rails spaced apart from each other, and posts fitting into the spaces between the ends of the side and end rails and bearing on said panel corners and having shoulders bearing against the adjacent ends of the rails at opposite sides of the corners of the box, substantially as described. In witness whereof, I have hereunto se my hand this 16th day of April 1906.
